For the old style I use a penny..... remove the blue bottom caps and put a penny at the bottom of the tube and push the clone thru with a pencil or something.....
With the popcicle cloner i put the penny in the bottom then fill with vermiculite......
Then use the drain hole to push the penny..
You should also be able to turn them over and tap them out ......if using the larger popcicle mold....
Once the clone dislodges from the cloner.... just lay it sideways and use the stem.....
